This is an interesting question, especially since so many children today are overweight (or obese) and we want to prevent this whenever possible.

We know that pregnant women with diabetes are more likely to give birth to babies who are larger than average because the fetus gets too much sugar from mom's blood. In fact, infants of diabetic mothers are often so large that they need to be delivered by C-section. Many of these babies go on to have normal weights within a few months after birth. However, research also suggests that babies born to mothers with diabetes have a higher risk of being overweight during childhood and adolescence and then developing diabetes later in life.

Remember that babies born to women who are overweight are more likely to become overweight as children and adults. Much of this may be due to their specific family eating and exercise habits. On the other hand, studies involving twins, adopted children, and large families point to an inherited risk for obesity. Scientists are looking for the genes that may be responsible.

In addition, women who are overweight are more likely to develop diabetes during pregnancy. So, babies born to women who have diabetes and who are overweight are more likely to go on and become overweight or obese.

Therefore, if you are overweight or have diabetes and are thinking of becoming pregnant (or are already pregnant), talk with your doctor today. Ask what you should be doing so that you can be as healthy as possible and reduce any health risks for yourself and your baby.
